>                 Key: DRILL-3697
>                 URL: https://issues.apache.org/jira/browse/DRILL-3697
>             Project: Apache Drill
>          Issue Type: Bug
>            Reporter: Daniel Barclay
>            Priority: Major
>
> The {{REGEXP_REPLACE}} function documentation currently at [https://drill.apache.org/docs/string-manipulation/#regexp_replace] says that {{REGEXP_REPLACE}} uses POSIX regular expressions.  
> Is that true (that Drill using POSIX regular expressions and not Java regular expressions)?
> If that's really true, are they BREs or EREs?
> Assuming it's actually Java regular expressions, the documentation should probably have a link to some appropriate target in the JDK Java doc (maybe http://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html and http://docs.oracle.com/javase/8/docs/api/java/util/regex/Matcher.html#replaceAll-java.lang.String-.
